Playful Kiss!

Do you ever have that someone that is way out of your leage?? Well what if fate is so cruel that you end up living with them... In a world separated by social standings and brains will Sarah Brooks ever be able to measure up to Nate Collins?? There school is separated by class A-F. A being the smartest and F being the dumbest. If Nate is in A and Sarah is in F how are they ever going to match up!? What if Sarah isn't as stupid as everyone thinks??
